Taken together, these data suggest that anti-inflammatory and anti-aging activities of Antarctic freshwater microalga, Micractinium simplicissimum, can provide new clues to understanding the molecular link between inflammation and diseases, and be a potential anti-inflammatory agent.The purpose of this study is to produce nanostructured lipid carrier (NLC) that can solubilize poorly water-soluble velutin and verify an improved tyrosinase synthesis inhibition. A solubility test for velutin was conducted. Cetyl palmitate and caprylic/capric triglyceride were selected as solubilizer. The lipid matrix was produced using the ultrasound dispersion method. The morphology and size distribution of the produced NLC was analyzed through scanning electron microscopy (SEM) and dynamic light scattering (DLS), and the release and tyrosinase inhibition of velutin was evaluated through the Franz diffusion cell method and tyrosinase inhibition assay. Lipid matrix nanoparticles showed an average size of approximately 250 nm and polydispersity of 0.2, and it was confirmed that the velutin incorporated within nanoparticles sustained release at a constant rate over 36 hours. Due to extremely low aqueous solubility, the tyrosinase synthesis inhibition of velutin suspension was 0%, and the value of velutin incorporated within the NLC formulation was greatly improved 56.5% (40 μg/mL). As a result, it was verified that lipid-based NLC nanoparticles are an efficient formulation for the topical delivery of poorly water-soluble flavonoids such as velutin.The aim of this study was to improve the skin accumulation of hydroxycitric acid by using ethosomes with nanosize. We fabricated nanosized ethosome for the topical delivery of hydrophilic hydroxycitric acid and evaluated their physical properties and furthermore cytotoxicity. As results, in cell-based experiments, the use of ethosomes encapsulating hydroxycitric acid extract reduced the lipid droplet deposition in differentiated adipocytes, which was visualized by Oil Red O staining assay and also quantitatively measured by a triglyceride assay. https://www.selleckchem.com/products/eg-011.html The observed reduction in lipid droplet deposition occurred in a hydroxycitric acid extract concentration-dependent manner. In addition, the high accumulation of hydroxycitric acid in murine skin (66.28%) was observed following treatment with hydroxycitric acid extract-loaded ethosomes compared with treatment with hydroxycitric acid alone (1.19%) without ethosome as a nanocarrier. Based on these results, our findings showed that nanosized ethosomes improved the topical delivery of hydroxycitric acid and thus reduced lipid droplet deposition in adipocytes.(PPh?)Mo(CO)5 and (PPh?)?Mo(CO)? were synthesized by the reaction of molybdenum hexacar-bonyl with triphenylphosphine and applied as precursors to hydrocracking of vacuum residue under high-pressure and high-temperature conditions. (PPh?)?Mo(CO)? could also be synthesized by the reaction of (PPh?)Mo(CO)5 with triphenyl phosphine. A commercial precursor (Mo-octoate) for hydrocracking of vacuum residue was used for comparison. The thermal decomposition behavior of (PPh?)Mo(CO)5, (PPh?)?Mo(CO)?, and Mo-octoate was also examined by the thermogravimetric analysis. The TGA curve of (PPh?)Mo(CO)5 and (PPh?)?Mo(CO)? showed a similar weight-loss pattern. (PPh?)Mo(CO)5 and (PPh?)?Mo(CO)? were decomposed into Mo metal and ligands rapidly in the range of 140 °C~270 °C. There were no ligands bound to a metal center of (PPh?)Mo(CO)5 and (PPh?)?Mo(CO)? at the reaction temperature (430 °C) of hydrocracking. The amount of coke formed after hydrocracking over (PPh?)Mo(CO)5 and (PPh?)?Mo(CO)? was 2.3% and 0.5%, respectively. Upgrading the qualities of heavy oils is an important issue in the energy industry. It is not easy to achieve the complete conversion of vacuum residue due to coke forming during hydrocracking of vacuum residue. This study showed that (PPh?)?Mo(CO)? was considerably effective in reducing coke formation.This study examined the thermal and catalytic pyrolysis of waste Achyranthes Root (AR) using pyrolyzer-gas chromatography/mass spectrometry (Py-GC/MS). The non-catalytic pyrolysis of waste AR produced various kinds of oxygenates, such as acetic acid, hydroxy propanone, furfural, phenol, cresol, guaiacols, syringols, and so on. By applying nanoporous Al-MCM-41 with acidic properties and mesopores to the pyrolysis of waste AR, the levels of furan and aromatic hydrocarbons production increased with a concomitant decrease in the other oxygenates. The formation efficiency of furans was improved further by increasing the amount of Al-MCM-41 applied to the catalytic pyrolysis of waste AR.The catalytic combustion of acetaldehyde was studied using various types of Co oxides and Co-PC. The Co oxides and Co-PC were characterized using an X-ray diffractometer (XRD), X-ray photo-electron spectroscopy (XPS), and a particle sizing analyzer. The Co-PC and CoO were converted into Co?O? under an air atmosphere at 450 °C, and the results were confirmed using the XRD and XPS. According to the pretreatment of the Co-PC and Co oxides, the conversion of acetaldehyde increased. The order of particle size for both fresh and pretreated samples is summarized as follows CoO less then Co-PC less then Co3O4 powder less then Co?O? (99.995%). For all samples, acetaldehyde was not observed at temperatures above 320 °C owing to complete combustion. The conversion of acetaldehyde in the samples was affected by the fresh state of the Co oxides and the space velocity. The catalytic activity depended on the chemical state of the Co oxides and the surface concentrations of Co, O, and N.Cadmium telluride (CdTe) nanoparticles (NPs) are known for their unique physical and chemical properties. NP synthesis via a size-controlled procedure has become an intriguing research topic because NPs exhibit novel optical and physical properties depending on their size. Their sizes and properties can vary depending on the types and concentrations of stabilizers, which are bound to the surface of the NPs and protect the NPs from aggregation. In this study, we synthesized CdTe NPs stabilized by thioglycolic acid (TGA), 1-thioglycerol (TGC), and L-cysteine (L-C). The ratio of stabilizer to Cd2+ was 12.4. Transmission electron microscopy (TEM), X-ray diffraction (XRD), and photoluminescence (PL) were employed for characterization of the NPs. The average sizes of the synthesized NPs were 4.2, 4.1, and 3.7 nm for TGA, TGC, and L-C, respectively. The maximum fluorescent emission peaks of the three NP solutions were at 554.9, 551.6, and 538.3 nm for TGA, TGC, and L-C, respectively. The produced particles were crystalline in structure with a face-centered cubic (fcc) system.
